Example exoatlas visualization placing the first discovered transiting exoplanet HD209458b in context with other transiting exoplanets and the eight major Solar System planets. Errorbars use a color intensity that scales

Atmospheric speciation of TRAPPIST-1e at 280 K above a planetary surface with stable condensates for atmospheres originally in equilibrium with a fully molten mantle. In all panels, the curve colours

The major COMs formation routes on grain surface. The COMs studied in our simulations have teal background. The species involved in the methanol formation chain are highlighted in bold. The

Interstellar Comet 3I/ATLAS — ESA / Las Cumbres Observatory Astronomers from ESA’s Near-Earth Object Coordination Centre (NEOCC), part of the Agency’s Planetary Defence Office, made these observations of the newly

A comparison of state-of-the-art geometric distances that serve to anchor the distance scale and their current relative uncertainties. Additional candidate (≲1 Mpc) eclipsing binary hosts to target in future are

Earth’s surface is shown as it might have looked some 3.8 billion years ago, perhaps when life was just beginning, in this artist’s rendering. Illustration: NASA/JPL-Caltech/Lizbeth B. De La Torre

The color shows the product of the radiation flux at a wavelength of 3 µm and the square of the distance for the case of a prograde fall of the

Site locations and hypothesized pan-Arctic glaciation. ODP Site 910 and MD99-2277 (red dots) are located in the Eurasian sector of the Arctic Ocean and central Nordic Seas, respectively. Site 910

Distance vs. Stellar Mass for over 15,000 known galaxies out to 50 Mpc (Ohlson et al. 2024). Galaxies are colorcoded by their Hubble “T” Type, with early type galaxies T
